Sleep intelligence
A camera-free room turns into a quiet data field: sleep stages, breathing, movement, noise, temperature, humidity and light — read at a glance each morning.
Raychel APP · Companion in your pocket
Sleep better.
Focus deeper.
Know your Raychel.
The companion app for Raychel NODBOT. Read the room without a camera, slow down with guided breathing, and shape the voice, memory and skills of the AI that lives beside your bed.

What it does
Everything Raychel senses,
in one calm interface.
Six connected spaces — sleep, focus, agent, voiceprint, device and lab — designed to feel quiet rather than clinical.
Breathing focus
Guided 4-7-8, 2-1-2 and 1-2-1 rhythms with a living focus tree. When your focus drifts, leaves fall; when the session ends, a report shows breath stability and heart rate.
Agent studio
Name your Raychel, choose the language model and memory, pick a text-to-speech voice, and enable the tools that belong in your home.
Voiceprint
Register the people who share your space. Raychel recognises each voice and can answer every member of the household in their own way.
Device control
Pair in seconds by QR code, check the room, trigger OTA updates and reach your device from anywhere through a privacy-first cloud relay.
Innovation Lab
Experimental skills from 3D-printed cap lights to AI-composed wake-up scores and a 28-language auto translator. New experiments land regularly.
Inside the app
Three moments, one companion.
01 · Morning
Wake up to evidence,
not guesswork.
The sleep screen opens with the night you actually had: a sleep score, total sleep, deep sleep, and the room conditions that shaped it. No camera, no wearable, no video leaving the room.
- Camera-free sensing — millimetre-wave radar and LiDAR read presence and breathing.
- Room context — noise, temperature, humidity and light intensity in one view.
- Sleep records — patterns across nights, so you can see what actually changes your rest.
02 · Daytime
Slow the breath,
watch the tree grow.
Choose a breathing rhythm and a duration. The focus tree responds in real time — steadier breath, fuller canopy. Afterwards, a report reads your breathing stability, heart rate trend and movement.
- Three rhythms — 4-7-8 Relax, 2-1-2 Afternoon Boost and 1-2-1 Quick Calm.
- Radar-sensed feedback — relaxation, sound variation and body movement over the session.
- Share the calm — turn a session into a poster and send it on.
03 · Personalise
A companion that learns
how you like to be spoken to.
Give Raychel a nickname, a voice and a memory. Register family voices with Voiceprint. Then step into the Innovation Lab to design a cap light, compose a wake-up score or try the latest experiments.
- Agent & voice — model, memory, TTS voice, speech rate and volume.
- Voiceprint — add each speaker with a name and description.
- Lab experiments — 3D DIY, desktop panels, translation, psychology and music scores.

Before you install
Good to know.
Which version should I choose?
On iPhone and iPad, use the H5 web app and add it to your Home Screen. On Android, the APK gives you the native experience; the H5 web app works there too.
Do I need a Raychel NODBOT?
You can create an account and explore the app first. Sleep sensing, breathing sessions and device control are powered by Raychel NODBOT once it is paired.
Is my data private?
Sensing is camera-free: no images or video are captured. Room and sleep data are designed to stay local-first, with the option of privacy-first cloud relay for remote control.
